At some point prior to the formation of Stargate Command, P7X-882 had a Stargate placed on its surface though, by the time it was visited by the Tau'ri, this was the only evidence of Ancient architecture on the planet. In addition to this, the planet had once been home to a population who wrote in cuneiform, specifically a dialect which was thought to be related to the Hittite language. These writings were known to exist in caves on the planet. (SG1: "Medical Considerations")
